Due to the growing population and advancing economy, medical waste accumulation has come to the attention of all facets of society. Although the issue of medical waste management planning has been addressed in developed nations, it still exists in several developing nations. This paper examines the effects of barriers under the Organization action, work handling, and Human Resource Practices section on the healthcare waste management (HCWM) sector in a developing country India. In this study, three hypotheses were constructed and tested using Structural equation modeling. The questionnaire was distributed among 200 health professionals to collect their responses. Ninety-seven responses were received, and 15 barriers were identified affecting the healthcare waste management sector. The results show that all three barriers (i.e., Organizational, Waste handling, and Human resources) hinder the Healthcare waste management sector. Organizational Barriers are the most significant among other barriers. So, the hospitals have to take appropriate actions to overcome these barriers. This paper helps to complete the research gap by providing the different characteristics of barriers. The development of a model for the analysis of barriers influencing HCWM is the Author’s original contribution.

“…Terahertz stone emits a vibration known as "terahertz waves," with a frequency like far-infrared radiation. When terahertz waves are directed towards the human body or substances, they may induce resonance phenomena, thereby increasing body temperature and vitality [6,7]. This research combines tourmaline and terahertz, printing them onto shirts, to explore the potential eff ects on individual heart rate variability when wearing shirts adorned with patterns of these two minerals.…”

Introduction: Expanding upon prior investigations that identified advantageous Far Infrared (FIR) properties associated with two minerals, namely tourmaline and terahertz, across diverse domains, including health and medicine. This study explores the impact of incorporating fine powders of these minerals into printing ink for patterns on shirts on HRV when wearing the shirts. Methods: A total of 12 healthy adult males were surveyed in this study. Fine powders of the two minerals, tourmaline, and terahertz were incorporated into printing ink and used to print patterns on shirts. The impact of wearing these shirts on HRV was observed. Result: The significant differences in time-domain analysis parameters such as SDRR and RMSSD, frequency-domain analysis parameters including Total (ms2), VLF (ms2), LF (nu), HF (ms2), and nonlinear analysis parameters SD1 and SD2 were observed. Conclusion: The findings suggest that both short-term and long-term wear of shirts containing these minerals lead to an increase in vagal nerve tension. Participants wearing shirts with mineral inclusions exhibited changes related to vagal nerve activity.

“…Large diversity of potential applications of terahertz (THz) radiation caused growth of interest concentrated around this field [1,2], nevertheless recently the main focus is on medicine [3][4][5][6], security [7] or automotive industry [8]. These cases require not only efficient focusing of THz radiation, but mostly also the ability of broadband working.…”

Thin and lightweight achromatic focusing elements with F-number close to 1 are desirable in many practical applications. We present the idea to use diffractive structures designed to work for the substantially increased THz frequency range. The paper analyses mono- and multi-focal lenses forming point-like foci as well as axicon and light sword optical elements focusing THz radiation into line segments located along the optical axis. We consider diffractive elements in a form of the first and the second order kinoforms having various thicknesses. Designed and fabricated elements were numerically and experimentally examined to verify their achromatic functioning. We present point spread functions (XY scans) and 2D energy maps (XZ scans) for different THz frequencies. Moreover, a diagram of chromatic aberration is created by registering energy distribution along the optical axis for different frequencies. The distance corresponding to the highest energy is chosen for each frequency. Therefore, we can compare broadband working of designed structures. The spherical lens coded as kinoform of the second order provides the best broadband functioning, however it is two times thicker than structures providing extended depth of focus (light sword and axicon) working with slightly smaller efficiency but being much thinner.
